چکیده
In ancient t imes, wax seals impressed with signet r ings were aff ixed to documents as evidence of their authent ic i ty . A digi ta l counterpart is a message authent icat ion code f ixed f i rmly to each important document. We sketch an archite cture that accompl ishes this by using encapsulat ion of content with provenance metadata, cryptographic seal ing, and webs of t rust rooted in respected inst i tut ions.

متن کاملSome relations between $L^p$-spaces on locally compact group $G$ and double coset $Ksetminus G/H$
Let $H$ and $K$ be compact subgroups of locally compact group $G$. By considering the double coset space $Ksetminus G/H$, which equipped with an $N$-strongly quasi invariant measure $mu$, for $1leq pleq +infty$, we make a norm decreasing linear map from $L^p(G)$ onto $L^p(Ksetminus G/H,mu)$ and demonstrate that it may be identified with a quotient space of $L^p(G)$. In addition, we illustrate t...
